Using a wall mounting method is the simplest and easiest method for DIY installation. Shutters can be mounted anywhere on the wall with the header box under the eaves, level with the window, slightly over the window or anywhere in between. We would however suggest where there are multiple windows next to each other, it is preferable to keep the positioning of the header box consistent between the windows for maximum visual appeal.

Automated DIY Roller Shutter Height Measurement

To measure the height of the roller shutter you simply need to take two measurements – one on the left side of the window and one on the right side of the window. Measure the height from the top of the window opening down to the bottom of the window opening or sill. If your window frames or architraves protrude out past the wall, then measure the height from the top of the frame/architrave to the bottom of the frame/architrave see Diagram A. Where window frames/architraves or handles protrude out beyond the wall you will need to use packers before mounting your roller shutters.

If your window is located directly underneath the eaves, measure from the bottom of the eaves to the sill to get your height measurement see Diagram B.

Always measure to the nearest mm. If your two measurements differ do not worry always use the larger of the two measurements.

The height you have just measured is the area that will be covered by the slats when the roller shutter is deployed. This is called the curtain height. However, the overall height of your roller shutter needs to include the header box, so you need to add the height of an appropriate header box onto your measurements.

Header boxes come in a number of different sizes, as the longer the window the more slats that need to be stored within the header box, therefore the larger the header box size required.

To select the correct header box size for your chosen shutter type, simply look up your curtain height (largest height measurement) below and select the header box that matches

Automated DIY Roller Shutter Width Measurement

To measure the width of the window simply measure the width of window opening at both the top of the window. If your window frames or architraves protrude out past the wall, then measure the width from left hand edge of the architrave to the right-hand edge of the architrave see Diagram A. Don’t worry of the two measurements differ simply use the larger of the two measurements. If your window frames or architraves protrude out passed the wall, then you will need to use packers when installing.

To calculate the overall width of your roller shutters you need to add on an allowance for the guides. To select the appropriate guide width simply take the larger of the two measurements, look up your shutter type and add on the amount given.
